On the outer space shuttle more than 400 kilometers, Xu Chuan was not very worried about the impact of the super typhoon observed this accident.

For China, there are perfect means and related measures to deal with the formation and monitoring of typhoons.

As long as you prepare in advance, the problem will not be too big.

After staying in low-Earth orbit for several hours, after completing the docking with the Tiangong Space Station and replenishing a batch of supplies for the space station, Xinghai also started its journey back.

As planned, under the instructions of the ground command, the aerospace engine restarted, and the main engine swaying at the tail of the space shuttle and the auxiliary engine on the flank emitting blue and white light, pushing the huge fuselage to complete the rail change and head towards the ground.

After completing the internal inspection of the space shuttle, Zhai Zhigang quickly came to the crew cabin and reminded Xu Chuan and two other "tourists".

"Academician Xu, Prince Faisal, and Mr. Abdul Rahman. Xinghai is about to return. Please put on the space suits in the cabin and be prepared."

Xu Chuan smiled and replied while struggling to wear the spacesuit in the cabin, "I'm already wearing it."

On the side, Prince Faisal, who was bearded, half of his body entered the space suit and complained: "This thing must be worn slowly, it's really troublesome!"

Zhai Zhigang looked at him expressionlessly and said, "For your safety, it is best to wear a space suit for your safety."

Honestly, he doesn't have much favorable feelings for the prince of the Middle East in front of him.

Although as a soldier himself, he should not have such a position, and everything acts with command and command.

But this time, Academician Xu Chuan and Academician Xu were fooled by this guy, but it also had something to do with him.

If something unexpected happens during this space trip, he will be the sinner of China and even the entire human civilization.

Prince Faisal shrugged, perhaps because he felt something, and did not speak anymore, and struggled to put on the spacesuit in the cabin.

Compared to the gravity-bearing environment on the earth, wearing this thing in gravity-free space is more troublesome than imagined. The group of people struggled for more than half an hour before they were fully worn.

At the same time, in the cockpit, Zhai Zhigang, who was ready, contacted the ground command center. Under the dispatch of the ground, he reached out and pressed several buttons on the control panel in front of him.

"The preheating of the aerospace engine has been completed, Xinghaidui is ready, and the navigation route has been determined..."

Accompanied by cold mechanical sounds, a silver-white space shuttle dragged a faint blue-white tail flame to create a perfect curve and flew towards the blue planet on the low-Earth orbit hundreds of kilometers high.

.........

For spacecraft, there are two most difficult places in the entire navigation process.

The first is to leave the gravity well and enter the low-Earth orbit, commonly known as "entering orbit", and the second is to return to the atmosphere from the low-Earth orbit.

To be strict, with current aerospace technology, it is more difficult to return to the air than to enter orbit.

Generally speaking, the spacecraft generally goes through four stages when returning to the ground, namely de-orbit, transition, re-entering the atmosphere and landing.

Because the spacecraft's flight speed is too fast, two major problems must be solved during the return process: one is to reduce air friction and not burn due to high temperatures;

The second is to use soft landing methods to prevent the spacecraft from being damaged.

These four points are a life-and-death challenge for traditional space shuttles or spacecrafts.

However, for Xinghai, which adopts more advanced propulsion technology, the difficulty of these three major steps has been reduced countless times.

The only danger is to re-enter the atmosphere.

It is not just because the spacecraft needs to be controlled to enter the atmosphere in a predetermined position and attitude, so that the reentry angle cannot be too large, and it will burn it too large; it cannot be too small, and it will not fall down too small.

In addition, the space shuttle enters orbit very fast. Even if it slows down in low-Earth orbit in advance, the friction between its fuselage and the atmosphere will still produce extremely high temperatures.

Multiple difficulties are a great test for the performance of the spacecraft itself and the driver's technology.

So whether it is a traditional spacecraft, a space shuttle, or other manned spacecraft, returning from low-Earth orbit is always a technical job.

In the cockpit, Zhai Zhigang and Chen Dong played a twelve-point spirit, and focused on controlling the Xinghai to enter the transition route.

The landing took not long. After the "off-orbit section" at a height of 160 kilometers to the high-rise atmosphere at a height of 50 kilometers, the speed of the Xinghai began to gradually decrease.

Soon, sufficient air in the atmosphere replaced the xenon in the wing working fluid box, and a red and purple tail flame reignited at the tail of the space shuttle.

Dragging a narrow and long flame, Xinghai, which entered the atmosphere from the northwest China, flew towards the east.

The landing address for this voyage is not in the Xiashu Space Center in Jinling, but will be located at a military airport in the capital.

The red and purple tail flames swayed in the air, particularly eye-catching in the blue sky and white clouds.

In the airport on the ground, Wu Yuankang of the Space Administration stood in the sub-control room of the airport, carefully waiting with an old man.

"Let's go, our 'hero' is back smoothly, go and have a look."

Looking at the scene coming from the surveillance screen in the sub-control room, the old man said with a smile, but the word "Hero" was a bit heavy.

Wu Yuankang nodded and walked out with him. Behind him, two medical staff were carrying a portable medical box on their shoulders and prepared for the examination.

It was not his idea to ask Xinghai to land in the capital, but the request of the person who was walking in front of him.

Maybe I want to ‘criticize’ that person’s adventurous spirit.

Although it is difficult for the senior management to change his ideas, and he is still half coaxed more often, if you don’t say a few words about this kind of adventure in space travel, he may be about to land on the moon next time.

This chapter is not over, please click on the next page to continue reading! Manned spacecraft is relatively safe in low-Earth orbit. Even if there is an unexpected situation in Xinghai, they have other spacecraft and launch vehicles to pick up people.

But landing on the moon is different. At present, the entire China has the ability to complete manned landing on the moon, which is the Xinghai space shuttle.

If the person thinks that space travel is actually dangerous, he will run to the moon with the space shuttle next time, it will be a big pit.

Of course, on the other hand, the medical staff here are asking them to carefully check their physical arrangements.

Although it is a short-distance low-Earth orbit and the Star Sea also has complete radiation resistance, space travel has some risks after all.

Compared with Jinling, the medical resources in Beijing are still much better.

......

The red and purple tail flames were like the brilliant sunset in the sky, and the silver-white starry sea appeared from the blue sky as white clouds.

A short time passed by like a weaving shuttle, and the swaying red and purple tail flames gradually disappeared on the spacious runway.

The engine was turned off, the deceleration parachute was sprayed backward, and the space shuttle was sailing slowly stopped.

In the cockpit, Zhai Zhigang's hand holding the control lever slowly released, and he also sat on the chair with a loss of strength, stretching the turbid air in his chest for a long time.

Although the mission this time was ordinary, it was the most worrying one of all the flights in his life.

Fortunately, everything went well.

In the crew compartment, when the space shuttle entered the atmosphere and returned to the embrace of Mother Earth, Xu Chuan had already taken off his space suit in the cabin.

When the plane landed smoothly, he stood up from the space chair and walked towards the soon-to-open the hatch door.

Looking at the blue sky, Xu Chuan felt a little satisfied and wonder.

Space travel, something he had never done in his previous life, was less than ten years after he was reborn and returned, and he stood at a height of hundreds of kilometers and overlooked the red land.

......

Walking down the shuttle along the gangway, no one came to greet them in the open runway of the airport, but it was obvious that at the distant post, there were many soldiers with live ammunition holding on to this place.

At this moment, a familiar old man walked over from the exit.

Seeing this person, Xu Chuan quickly walked over and said hello: "**, why are you here?"

The old man looked him up and down, and then smiled and said, "Is it fun above?"

This is probably the first person in the history of aerospace history who dares to take the space shuttle he designed and manufactured.

After all, manned spaceflight is not usually high for astronauts' physical fitness requirements. Traditional chemical fuel rockets can accelerate to 6 or 7 G when launched and returned.

Most ordinary people who have not been trained cannot withstand this super-strong acceleration.

"Forehead....."

Hearing these words that seem to be criticized and inquired, Xu Chuan was hoarse for a while, thinking for a long time before replying: "It's okay..."

The old man shook his head and sighed, "You, you are so brave. If something happens, how can you tell me to explain to your parents."

"It's not that you won't let you go up. At least as our aerospace technology has just started, we can wait a little longer."

"You are still young, even if you have dreams, what if you wait for another two years..."

Looking at Xu Chuan, the man was shaking his head like his parents and elders, and kept nagging.

Standing aside, Xu Chuan's face was embarrassed, neither listening nor not listening. He wanted to leave but couldn't leave, and he was almost irritated by the chanting.

This is probably the first time someone other than his parents is nagging him like this, and he can only stand there and listen.

Fortunately, it was not long before Prince Faisal got off the space shuttle and Abdul Rahman of the UAE helped him to clear the siege.

After all, he is the prince from the Middle East. Since he has arrived, the old man still has to say hello friendly.

"Huh~"

He breathed a sigh of relief. Xu Chuan, who had escaped the communication between the two sides, was about to slip away quietly, but was stopped by Director Wu Yuankang from the Space Administration.

After falling from outer space hundreds of kilometers high, you have to have a comprehensive physical examination no matter what.

Although he felt good about his physical condition, he could not stand the request of his superiors. Xu Chuan and Prince Faisal, who went to heaven together this time, were taken to the 301 People's Liberation Army General Hospital and were admitted to the hospital.

After greeting various instruments and equipment, they almost got acupuncture.

Although he was not interested in these things, Xu Chuan also knew that it was for his own good. After all, he went to outer space and did not worry about it if he did not check thoroughly.

Fortunately, although he was staying in the hospital, his daily activities were not restricted.
